hmm if you're running rich that means the ecu could be fried... Check you're spark plugs and see if their wet with gas. And if your running really rich you'll see black smoke out the exhaust. Or it could be your tps, it thinks your wot, so it dumps a load of fuel in, but your not wot.

tps throttle position sensor. real expensive unless u find one on ebay or the junkyard. i think it is pop riveted onto the tb but im not sure all i know is the dealer wont let u buy it without the throttle body

The throttle positioning sensor tells the ecu if you're at wide open throttle or part throttle, so it knows how much fuel to dump in(I know there is more to that, but it is a basic rundown.). Or you're vacuum box could be broken, and you can run constantly rich. I had both these problems at once, so it wasn't good. And the tps is riveted on.
